The only problem I see the zombies having against that army is if they pod up around Raelin on height. The wyverns can get eat up by the protectors, but I'm betting that if they get Raelin out of position the zombies can handle everything.

Everyone but Isamu is immune to both Talon Grab and Zombies Rise Again. Get Zetacron on height to snipe the Wyverns, then send in the Templars to smash the Zombie horde. Nilfheim can lend a hand wherever he's needed.

Van Nessing and the Incendiborgs take down Cyprien. Finn goes out to destroy as many Greenscales as possible, then goes on Krug's card when he dies. Isamu's Dishonorable Attack tenderizes Nilfheim a bit, and then boosted Krug and any remaining Soulborgs mop up anyone left alive.

Use Me Burq Sa to take shots at Repulsors, maybe landing a lucky Paralyzing Stare on Migol. Otherwise, this army just uses it's extreme numbers to fight back the Dwarvern Horde. Superior Defense along with some D20 action should get the job done. Since none of the figures you have can shoot well, Marcus should have no trouble sticking around to grant that nice +1 Attack.

Send the Marro to height and shoot down MBS. Send Charos and the Lizardfolk to meet the Romans and their warlords head-on. Charos plus buffed Greenscales should overcome their enemies. Use Marro as cleanup if needed.

Kursus makes the opening strike, using his Sonic Fists SA to weaken Charos and take out some of his cronies. Once he dies, use the Gruts as an OM dumping-ground. Rain arrows indiscriminately while using Mimring to help take out the remaining squad members. Then send in Krug to finish of Charos.
